,TBOLLEY AND. SIGNAL WIRE HANGER.

Application filed November 7, 1923. Serial No. 673,332.

To all arms may concern."

Be" it known that I, ALBERT J. G'URNEY, citizen of the United States, residing at Canton, in the county of Stark andJState 5 of Ohio, have invented certain new and useful Improvements in Trolley andSignal Wire Hangers, of'w'hich the following is aspecification. j' 1 This invention relates 'to an improved trolley and signal wire hanger for mines as employed in my improved'signaling system forv minesfiled November 7, 1923, -Ser. "No. 673,329, and seeks, as one of'its objects, to provide a hanger which, inaddltionto supportinga trolley; wire, will also sustain a conductor-wire over the trolley wire in close spacedrelation thereto.v

Theinvention seeks, as a further object, to provide a hanger wherein the wires may be readily attached thereto to be firmly held bythehanger.

,And the invention seeks, as a still further object, to provide awhanger embodying clamping means common to both wires for binding the jaws of the hanger n engagementtherewith.

Other and incidental objects will appear hereinafter. j In the drawings:

' Figure lvis a s'idejelevation of my improved hanger, parts being broken away and; shown in section, and.

Figure 2 is a sectional view particularly showin the structure of the clamping aws r of the anger.

In carrying the invention into elfect, I

I employ an insulator-10 which may be of 7 any approved construction but will include a depending stud 11 and may be suitably other supporting means such, for instance, as a oross beam 11' in the mine. Detachably connected to the stud are companion elongated clamping jaws 12 and 13 grooved r at their lower margins to receive a trolley wire therebetween, as conventionally illustrated at 14. Centrally thereof, the jaws are channeled at their inner sides to define mating portions of a longitudinal bore between the jaws and fitting in said bore is a sleeve 15 of suitable insulating material, the sleeve accommodating a conductor wire 16. Formed on the ends of the jaws to snugly surround the ends of said sleeve are secured directly to the roof of a mine or themating halves of conical nipples 17 and threaded over said nipples are nuts 18 n which, as'will be perceived, may be adjusted for clamping the jaws in engagement with the sleeve 15. Rising from the jaw 12 medially thereof is a cylindrical shank 19 overhanging'the jaw at its inner side and cutaway at its upper end along the outer side of said shank to define a terminal boss 20. As shown in Figurev 2, the jaw 13 is formed medially with a transverse channel 21 and rising from the jaw to produce a continuation of said channel is a semi-cylindrical sleeve 22 extending about the shank and. providedat its upper end with a ring 23 fitting over the boss 20, the channel 21 permitting the jaws 12 and 13 tobe assembled. Thus, the ring 23 will normally maintain the. jaws in assembled relation, and formed in the shank 19 is an axial socket accommodating the stud 11. Accordingly,

the jaws may be readily attached to the insulator when, after the wires 14 and 16 be applied for tightening the jaws. As will .be noted, the hanger is constructed to suphave been arranged inplace,the nuts 18 may improved signalingsystem previously. identified, suitable annunciators are electrically connected with the wire 16 so that when the trolley wire is pressed upwardly by the passage ofa mine car trolley along the trolley .wire,-a circuitwill be closed through the wire 16 for energizing the annunciators.

Having thus described the invention, what is claimed as new is:

1. A hanger of the character described including coacting jaws to engage a wire, and independently adjustable means rotatably mounted on the opposite ends of the jaws and positively engaging said ends for securing the jaws together. 2. A hanger of the character described in cluding coacting jaws to engage a wire and formed to receive a second wire therebetween, means accommodated between the jaws insulating the latter wire from said first mentioned wire, and means for drawing the jaws toward each other.

, 3. A hanger of the character described including coacting jaws to engage a wire and channeled to receive an insulator therebetween accommodating a second Wire, and

means for drawing the jaws toward each other about said insulator gripping said first mentioned wire.

4. A hanger of the character described in eluding coacting jaws to engage a wire and provided at their ends with threaded nipples, and nuts screwed upon said nipples clamping the jaws in engagement with the wire.

5. A hanger of the character described in cluding companion jaws provided at their ends with nipple portions mating to define nipples at the extremities of the jaws, and nuts screwed upon said nipples and adjustable for clamping the jaws in engagement with a wire.

6. A hanger of the character described including coacting jaws channeled to receive an insulator therebe-tween accommodating a wire and provided at their ends with nipple portions mating to define nipples surrounding the ends of the insulator, and nuts adjustable upon said nipples for clamping the jaws about the insulator.

7. A hanger of the character described ineluding coacting jaws channeled to define 'a bore therebetween and provided at their ends with nipples, an insulator fitting in said bore and adapted to accommodate a wire therethrough, and nuts adjustable upon said nipples for clamping the jaws about the insulator.

8. A hanger including companion jaws to coact with a wire, one of the jaws being formed with an overhanging shank terminating in a boss and the other of the jaws being formed with a sleeve to accommodate said shank and provided with a ring to fit over said boss connecting the jaws with each other, and means for drawing the jaws together.

-9. A hanger of the character described in cluding coacting jaws to engage a wire, and rotatable means independently adjustable longitudinally of the jaws for drawing the jaws toward each other.

10. A hanger of the character described including coacting jaws to engage a wire and formed to accommodate a second wire therebetween, and means adjustable longitudinally of the jaws for drawing the jaws toward each other.

11. A hanger of the character described including coacting jaws to engage a wire,

and rotatable means straddling the ends of the jaws and independently adjustable for drawing the jaw-s toward each other.

12. A hanger of the character described including coacting jaws to engage a wire and formed to receive a second wire therebetween, and means straddling the jaws securing the jaws together.

13. A hanger of the character described including coacting jaws to engage a wire and provided at their ends with threaded terminals, and rotatable means screwed upon said terminals securing the jaw-s together.

let. A hanger of the character described including coacting jaws to engage a wire and formed to receive a second wire therebetween, the jaws being provided at their ends with projections, and means straddling said projections securing the jaws together.

15. hanger of the character described including coacting jaws to engage a wire, one of the jaws being formed with a shank pro vided at its upper end with a terminal boss and the other of the jaws being formed with a ring to surround said boss resting upon the upper end of said shank for sustaining thelatter aw against downward movement relative to the former jaw, and means securing the aws together.

16. A hanger of the character described including coacting jaws provided at their ends with nipple portions mating to define nipples at the extremities of the jaws, and independently adjustable means fitting over said nipples securing the jaws together.

In testimony whereof I ailix my signature.
